Our new "Nomad & Extreme Series" A343F 4 Speed Prado and 80-100 Series Toyota Land Cruiser Heavy Duty Valve Body makes all the difference. Often we hear owners constantly complaining about the quality of their 4 Speed Toyota A343F Automatic Transmission when shifting through the gears.Most come from everyday drivers who simply can't stand the constant slipping and flaring between the gears. We have had dozens of owners contact us about improving the transmission in some way to overcome the problem. We put together a development program and have come up with a cheap and easy way to turn your A343F 4 Speed Toyota Land Cruiser Automatic Transmission into a nice crisp shifting transmission without having to remove the transmission from the car. Simply remove the valve body and exchange it for one of our Heavy Duty Recalibrated “Stage 1 Nomad” or “Stage 2 Extreme” Series of A343F Valve Bodies.

The new valve body comes with easy to read instructions for the removal and refitting of the new valve body. The valve body has undergone a tremendous amount of testing including anything from a basic engine upgrade, right up to the Turbo Charged and Super Charged and in every single case the customer has been quite overwhelmed about the difference the New Heavy Duty Valve Body made to the vehicle.

The transmission once fitted with the new Heavy Duty Valve Body can easily handle twice the power and torque while also greatly increasing the cars towing capabilities. All this with nice crisp shift points even while towing. We simply couldn't fault the new Heavy Duty Recalibrated Valve Body no matter what we did to it.
